Divide participants into equal groups, ensuring that at least one member of each group has a smart device with GPS capabilities. Teams will have one hour to find as many geocaches as they can. Explain to the group that geocaching is like a scavenger hunt, but you use GPS coordinates to find items. Have teams reveal their findings at the end of the activity. 
 Actually, it should be a one-to-one conversion ratio, but very few caches are easy.  As with real scavenger hunts, some elements are common to many caches, and some are specific to the individual cache. For example, a cache could have a note about the cache owner where he or she discusses the cache description, but it could also have a hidden coin for a few caches that only the cache owner is aware of.
3. Photos are acceptable, but video is preferred! Video helps the finder get a feel of the field to see what other people are finding and provides a record of what people are seeing. So long as that video cannot be redistributed (copied and distributed), it is not considered a violation.
4. Have caches hidden somewhere visible. Have the locations of the hides be publicly posted on the geocaching.com website. You may choose what the locations be. You could have some locations listed as "underground," other locations listed as "ground," etc. Discuss what you think the best locations should be. Then get players to vote for the final locations on their smart devices. d2c66b5586
